Exactly right.
I am much taller but if I try to touch the ground while sitting on the seat only my toes will touch unless I lean the bicycle over. The same for mounting as I lean bicycle to mount. I believe it's a fundamental skill when learning to ride a bicycle.
This is normal on a conventional bicycle that is adjusted properly to give the necessary leg extension while riding/pedaling.
